Hi Michael,
If you use an original 'ethernet.tdf' config file
That is
% egrep -v '(#|^\s*$)'
$ECOS_REPOSITORY/devs/eth/synth/ecosynth/current/host/ethernet.tdf
synth_device ethernet {
eth0 ethertap tap3 00:FE:42:63:84:A5
max_buffer 32
}
Let's notice that *ethertap* tap3 interface is used there.
Have you configured 'tap3' interface? Have you configured DHCP server on
the interface? If you done it, Can you get IP address from DHCP pool on
the interface:
% sudo dhclient3 tap3
There should be no surprise for you that if you want to use DHCP for
synthetic target you have to configure and networking too.
Well, I can guide how to get it working on Ubuntu, but I doubt that this
list is the appropriate place for this.
